About the flag

This is the flag of the city of Novosibirsk according to
nps.hotmail.ru/gerb.htm.
The flag is obviously derived from the coat of arms. Here’s the description:

The flag is divided diagonally from upper right to lower left corner by
blue belt with white waves. Left upper field is green. Lower right field is
white. Colors of flag were taken from city arms and
mean: green field —
health, nature wealth (resources) of Siberia, white field — purity and
snow of Siberia, blue belt with white waves — river Ob’, on which
the city is situated.

Interesting … the white-green characteristic for many
Siberian flags reported is retained,
as well as the blue that seems to be the third colour of the
“general rule”.Željko Heimer, 08 Apr 2000
